Front right tire is loosing air in one day that the tire becomes completely flat. I've had to reclean the rims before because of rim oxidation. I hope this is the same problem and not a tire leak. They are 4 Bridgestone Fuzion HRi 205/55R16 91H tires with 22,000 km on Audi A6 rims, I want to sell these 4 rims and place the original type 44 rims on the 86 Quattro. Max
